COKEOVEN-CLEARING MECHANISM.

Application filed April 17, 1920. Serial 1%. 374,537.

To all whom. it may concern:

Be it known that I, DAVID FERGUSON, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny 6 and State of Pennsylvania, have made a new and useful Invention in Coke-ven- Clearing Mechanism, of which the following is a specification.

This invention relates to mechanisms for clearing coke ovens and has for an object to produce a simple and effective mechanism in which the entire coke drawing operation is accomplished by means of power driven apparatus.

A further object is the production of a power actuated coke drawing or similar apparatus which is simple and effective in operation and which may be manipulated and controlled by a single operator.

These and other objects, which will be made more apparent throughout the further description of the invention, are attained by means of a mechanism embodying the features herein described and illustrated in the drawings accompanying and forming a part hereof.

In the drawings Figure 1 is a perspective view of a mechanism embodying my invention and shown in connection with a dia- & grammatic view of a coke oven, a track on which said mechanism is movably mounted and a fragmental view of a car into which said mechanism discharges. Figure 2 is a side elevation of apparatus forming a detail of my invention and which is a slight modification of similar apparatus shown as a part of the mechanism illustrated in Figure 1. Figure 3 is a view illustrating a portion of the operating mechanism forming a part of my invention.

Referring to the drawings:

The apparatus illustrated includes a frame 6 which is provided with wheels? adapted to run along a track 8. A carriage 9 is pivotally mounted on the frame and forms a sup port for a ram 10, which is movable longitudinally with relation to the carriage. The forward end of the ram carries a breaker 11, which is adapted to be moved into engagement with the mass of coke contained in a coke oven and to break up the coke for the purpose of facilitating its removal from the oven. The ram also carries means for removing from the oven the particles of coke freed by the action of the breaker. The means illustrated consists of members 12, similar to rakes, which are secured to endless chains carried by the ram and which are adapted to accomplish a raking action across the floor of the coke oven and to thereby deliver through the door of the oven the coke particles freed from the coked mass within the oven. The frame 7 also carries an apron 13 which is adapted to be moved adjacent to the lower edge of the oven door and to form a slide over which material removed from the oven is delivered to a conveyer 14 mounted on the frame. A chute 15 is located at the delivery end of the conveyer and receives material delivered by the conveyer and directs it into a car 16 or other receptacle. The mechanism illustrated is self-propelling along a track 8 and is provided with power actuated means for accomplishing this and also for advancing and withdrawing the ram, for actuating the breaker 11, the members 12 and the conveyer 14c and for swinging the carriage 9 to different positions with relation tothe' frame 6.

The frame 6 may be of any suitable construction and as illustrated is provided with four wheels 7 of the form ordinarily used in connection with railway cars. carriage supporting superstructure is rigidly secured to the frame 6 and consists primarily of vertical uprights 17 which terminate in and are secured together by an arched top member 18. Cross struts 19 and 20 are secured to and extend between theuprights 1 7 and form a support for a king-pin block 21 which forms a part of the carriage 9, is lo cated between the struts 19 and 20 and engages a king-pin 22, which is suitablysecured to the struts '19 and 20 and pivotally secures the carriage 9 to the frame 6. As illustrated, the carriage 9 includes two channel irons 23 and 23 which embrace and are rigidly secured to the king-pin block 21. These channels are also secured together, preferably in parallel relation, by means of plates or other suitable tie members. The carriage also includes two pair of ram hangers 2 L, one pair mounted at the forward and the other at the rear end of the carriage. Each of these hangers is secured at its upper end to one of the channels 23 or 23 the hangers co-operate in supporting the ram 10. As shown in Figure 1, the hangers of each pair are secured together by means of cross bolts or tie members 25 which perform the double function of securing the hangers together and of supporting the ram.

The ram is preferably formed of two lateral and longitudinally extending channel members which are secured together by means of a top plate 27 and other suitable stiffeningor bracing members. he ram extends longitudinally of the carriage and is located between the tie rods 25 of eachpair of hangers. As shown in Figure 2, the lower tie rod 25 of each pair may be provided with rollers 28 on which the rack is supported, and the upper tie rods may be provided with similar rollers 29 which are adapted to engage the upper face of the ram and thereby hold the ram against vertical displacement. In Figure 1 I. have shown each hanger provided with a roller 29 so located and arranged as to engage a lateral face of the ram. With this arrangement, the ram is held between two sets of such rollers and, therefore, lateral displacement is prevented.

As illustrated, the breaker 1.1 consists of two sets or curved knives or prongs 30. Four such prongs are included in each set and the two sets are secured together by, or are mounted on a drum 31. As shown in Figure 1,, each set o'l prongs is mounted on the axle of the drum 31 beyond. the supporting members 32 of the axle. gure 2, however. shows the prongs secur d to the drum 31. As illustratech the m here 32, in effect, form an extension ofthe ram, since they are secured to the forward end of the lateral channels forming a part of the ram.

The breaker is actuated by means of two endless chains 33, each of which is carried on a sprocket 34: journaled at the rear end of the ram and a sprocket 35 secured to orforming a part of the drum 31. The sprockets are so located and arranged that the chains are located in parallel relation and extend the entire length oi": the ram. As shown, these chains co-operate in actuating the members 12.

Each member 12 consists of a rake-like head 87, an arm 38 and a supporting rod 39 preferably integrally formed with. the arm 88. Each end of the supporting rod 89 is pivotally secured to one of the chains 33 and the chains co-operate in moving the members 12 across the top plate. 27 of the ram toward. the breaker 11 and below the and all ram away from the breaker. he pivotal support for each member per s the rake: like head 3'? to drop into engagement with the floor of the coke oven after the menber has moved across or around the dr The ram is provides. with a Figure which is engaged and which co-opera es moving the ram longit l to the carriage.

As shown, the i be secured to one of the lateral me the ram in such a way that the .auera member forms a lateral shroud for it.

The chains 33 are driven by means of sprocket wheels 42, which are mounted on shatt L3 journaled in su le brackets formed on or secured to the s 24. As shown in Figure 2, the sprocket 42 may be driven by a motor 414twhich is mounted on the carriage 9 and wnidt may receive power from a line-wire 45 through a trolley 46. mounted on the arched sun-pelt 18. As shown the shaft of the motor is brovided with a worm A? which n'ieshes with a worm wheel l8 mounted on shaft 49. The shaft 4: is provided with a bevel near 50, which meshes with a bevel ear 51 mounted on a shaft 52.

The shail. 52 is journaled in suitable brackets carried h the hanger and is provided with "we bevel gears 53 andbi, the first of which meshes with evel gear which drives the gear ll and the second of which r eshes with a bevel syear which drives the sprocket l2. d

The pivotal motion of the cru'ria e about the king-pin 22 is accomplishet by means or an arc-shaped rack 55 rigidlv secured to the uprights 17 of the suuerstri and a pinion 56 journaled on the c' and driven by the motor lll'liOll.. agency of bevel gears *7" .i l 523. a shat and bevel gears 60 and. (ii. will of course. be understood that sui..- a e clutch I nism is employed between shaft 1) each of the bevel 53. and 5'2. so that the motor a l is capable of independently operating the breaker 11 and the moi" l a :2 or of advancing and withdrawing: I or of swingin the carriage about 22. In Figure 3 l have illusria'i clutch members. it will. of course, be unden stood that each of the gears in question is rotatably mounted. on the sha't't i d tl a the co-operating clutch member =85 sp r to the shaft and is capable of being moved longitudinally thcr of to engage c sengage its copper gear. it will also be understood that each member ma I be operetirely connected to a separate operating lever located at a con enient point near the operators platform, so that the o 'ierator may control the several functions of the re- 1. These operating levers and the connecti links are omitted for the sake of clearness.

The main frame .6 of the mechanism ,carries the conveyer 14. ,As shown, the, conveyer includes two side members which are supported in parallel relation on the frame 6 and which support a large mesh screen or grill work 66, which secures the lateral members together and thereby stifiens the frame of the conveyer 14. A pair of sprockets 67 are located at the delivery end of the conveyer frame and a similar pair of sprockets 68 are located at the receiving end of the conveyer. Each pair of sprockets is mounted on a suitable shaft and each sprocket is located adjacent to one of the lateral members of the conveyer frame. These sprockets co-operate in mounting endless chains 69 which carry the conveyer cleats 70. It will, of course, be understood that any type of conveyer belt may be employed which is suitable for conveying relatively hot coke particles. An electric motor 71 is mounted on the frame 6 and is coupled or other wise secured to a shaft 72 which extends transversely across the frame and carries a sprocket 73 for transmitting power to the propelling wheels 7 of the mechanism. A gear 74 for transmitting power to the conveyer 14 is also mounted on the shaft. The sprocket 73 is shown operatively connected to a sprocket 75 by means of a chain 76. The sprocket 75 is rigidly mounted on the axle of the propelling wheels 7. The gear 74 meshes with. a gear 77 mounted on a stub-shaft on which a sprocket 78 is also mounted. The sprocket 78 is operatively connected to a sprocket 79 by means of a chain 80. The sprocket 79 is rigidly mounted on the shaft of the conveyer supporting sprockets 68. If it is desirable to transmit power directly to each pair of sprockets 67 and 68, the shaft of the sprockets 68 may be geared to the mounting shaft of the sprockets 67 by means of a shaft 82 and suitable bevel gears such as are illustrated at 83 in Figure 1.

The delivery chute or hopper 15 is shown suspended from extensions 84 secured to the delivery end of the conveyer 14. In the drawings I have shown a support85. secured to one of the rear hangers'24. This support may be employed as an operators platform or it may be employed as a support for a larger platform, which may extend between hangers of the front and rear sets.

It will, of course, be understood that each of the motors 44 and 71 is provided with a controller located in a convenient position with relation to the operators platform and that the sprocket 73 and the gear 74 will be provided with clutches similar to the clutches illustrated in Figure 3, so that the motor 71 will be capable of independently driving the conveyer l4 or-the wheel 7 ofthe mechanism. Itlwill, of course,

of the members 12 r The grill work be understood that the motor 71 receives cur rent from the line-wire 45.

The conveyer is moved to a position along the track8 opposite to the coke oven from erative as a power delivering agent and the clutch member associated with the gear 74 is moved to operatively lock that gear to the shaft 72. This operatively connects the conveyer to the motor 47. The clutches associated with the gears 53, 54 and '57 (Figure 3) are then set so that the gear 53 is operatively coupled to the shaft 5.2, Where as, the other gears mentioned are operatively disconnected from the shaft. The motor 44 is then started in a direction to advance the ram through the open door of the coke oven. As soon as the ram is in the desired position, the clutch associated withthe gear 53 is withdrawn and the clutch associated The operation of the apparatus is as foland by dliven As soon as with the gear 54 is moved to the operative 7 position. breaker 11 and the'members 12 through the agency of the sprockets 42 and'chains 33. It will, of course, be apparent, that it'is desirable to so gear the driving mechanism of the chains 33 that the breaker may be placed in operation after advancing the ram without reversing the motor 44. The breaker is continually pressed into engagement with the .mass of coke within, the, oven by advancing or by swinging the ram. As has been said, the swingingof the ram is controlled by the gear 57 and the clutch mem ber 65 associated with it and is accomplished through the be desirable to employ a reversing gearin the gear train between the motor'44 and the pinion 56, so that the rotation of the pinion may be reversed without reversing the direction of the rotation of the motor.

The coke loosened by the breaker is conveyed across the floor of the coke oven by means of the members12. It will, of course, be apparent that the supporting arms 38 are so proportioned .as to length as to-insure a raking action across the floor of the coke oven. Theloosened particles of coke propelled by these members 12 are delivered'to the apron 13 over which they move by gravity to the conveyer 14. 66 forming a part of the frame of this conveyer acts as a screen for the material moved across it by the conveyer cleats 7 O and thesmall material, there- This transmits power to the agency of the motor 44, pin ion 56 .and the arc-shaped rack 55. It may 70 which the coke is to be drawn. This isacfore, drops to the space between the rails whereas, the large commercial size coke is delivered by the hopper 15 to the car 16. In the drawings I have shown a lamp 87 mounted on the forward end of the carriage 9 and arranged to direct a beam of light into the coke oven. It will be ap parent that this lamp may receive current from the line-wire 45 and that the swinging of the carriage directs the light in such a way as to aid the operator.

\Vhile I have described this invention as particularly applicable to a mechanism for clearing coke ovens, it will be apparent that apparatus embodying the invention may be used for other purposes and that various changes, additions, omissions, modifications and substitutions may be made in the appatus illustrated without departing from the spirit and scope of the invention as set forth of the track,
